County Impact Statements - St. Francis County
County Resistant Weed Tour
The glyphosate weed control technology has been used the past 8 -10 years to control weeds in cotton and soybean production. Over the past 2 - 3 years, marestail and pigweed have become resistant to this herbicide. Cotton and soybean fields that were once clean from these weeds are now grown up in weeds. New weeds that are tolerant to glyphosate are being found each year.
The Weed Tour was conducted on the Rusty Carter Farm just east of Marianne in Lee County. Counties involved in the Weed Tour included Lee, Monroe, Phillips and St. Francis. Participants who attended the Weed Tour will use a pre-plant herbicide in 2009 to help control resistant weeds. Some will also use a new Liberty Link technology that looks very promising. Both were observed at the Weed Tour.
Producers learn new ideas on how to control resistant weeds.
